This 360-degree horizontal, 179.3-degree vertical view of the Holocaust Memorial in Berlin, Germany, consists of 2711 concrete slabs ('stelae') covering 19 000 square metres (4.7 acres). It stands to represent all the murdered Jews of WWII in Europe.
Cited from Wikipedia: "the stelae are designed to produce an uneasy, confusing atmosphere, and the whole sculpture aims to represent a supposedly ordered system that has lost touch with human reason."
